2 cups Chicken broth — Low sodium
2 tablespoons Palm sugar — Finely chopped (can substitute brown sugar)
3 tablespoons Fish sauce — To taste
1 tablespoon Light soy sauce

Noodles & Garnishes

1 pound Fresh flat egg noodles (Bamee) — Divided into 1/4 for frying and 3/4 for boiling
2 cups Vegetable oil — For frying the crispy noodles
0.5 cup Pickled mustard greens — Rinsed, squeezed dry, and chopped

Instructions

Prepare the curry paste: In a mortar and pestle or a small food processor, combine the soaked chilies, chopped shallots, garlic, ginger (or galangal), turmeric, ground coriander, ground cardamom, and curry powder. Pound or blend until a smooth paste forms. If blending, add a splash of water or oil to help the blades catch.
~10 min
For an authentic texture and deeper flavor release, using a mortar and pestle is recommended over a food processor.
Fry the crispy noodles: Heat the vegetable oil in a medium saucepan to 350°F (175°C). Take 1/4 of the fresh egg noodles, loosen them, and fry in small batches until golden brown and crispy (about 1-2 minutes). Transfer to a paper towel-lined plate and set aside.
~10 min
Watch the noodles closely, as they can quickly burn once they start to brown.
Fry the curry paste: Scoop off the thick cream from the top of the cans of coconut milk (about 1 cup) and add it to a large heavy-bottomed pot over medium heat. Cook until the cream reduces and the coconut oil begins to separate and glisten on the surface (about 5-7 minutes). Add the prepared curry paste and fry, stirring constantly, until highly aromatic, about 3-5 minutes.
~12 min
If your coconut milk doesn't separate, simply add 1 tablespoon of vegetable oil to help fry the paste.
Braise the chicken: Add the chicken drumsticks or thighs to the pot and toss to coat in the curry paste. Cook for 2-3 minutes to sear slightly. Pour in the remaining coconut milk and the chicken broth. Bring to a gentle boil.
~5 min
Simmer the soup: Reduce the heat to a low simmer. Season with the palm sugar, fish sauce, and light soy sauce. Cover partially and simmer until the chicken is tender and cooked through, about 30-40 minutes.
~35 min
Taste the broth near the end of the cooking time and adjust seasoning. It should be rich, slightly sweet, salty, and aromatic.
Cook the soft noodles: Bring a separate large pot of water to a boil. Cook the remaining fresh egg noodles according to package instructions (usually 1-3 minutes). Drain well and divide the soft noodles among 4 deep serving bowls.
~5 min
Rinse the boiled noodles quickly under warm water to remove excess starch so they don't clump.
Assemble the Khao Soi: Ladle the hot curry broth and 1-2 pieces of chicken over the soft noodles in each bowl. Top generously with the crispy fried noodles.
~3 min
Serve: Serve immediately with small separate bowls of chopped pickled mustard greens, sliced shallots, lime wedges, fresh cilantro, and chili oil on the side, allowing diners to customize their own bowls.

The contrast between the rich broth and the sharp/sour garnishes is essential to Khao Soi, so don't skip the pickled mustard greens or lime!

Tips & Storage

Store-bought yellow curry paste or Khao Soi paste can be substituted for the homemade paste to save time. Just use about 3-4 tablespoons.
Bamee noodles are fresh Chinese-style egg noodles available at Asian grocers. If unavailable, dried wide egg noodles or linguine can work in a pinch.
Pickled mustard greens are usually sold in plastic pouches at Asian markets. Be sure to rinse them, as they can be very salty.
Storage: Store the broth with chicken separately from the boiled noodles, crispy noodles, and garnishes in airtight containers in the refrigerator for up to 3 days. Reheat the broth gently on the stove. Boil fresh noodles if possible, as stored cooked noodles may become mushy.
